arXiv:2606.18319v1 Announce Type: cross Abstract: Air Traffic Control Operators (ATCOs) are vital in ensuring the safe, orderly, and efficient flow of air traffic, yet training capacity is constrained by reliance on specialized human trainers known as simpilots, who must role-play both pilots and ATCOs in a simulated airspace. Existing automated solutions rely on Western-centric speech models that perform poorly in Singaporean operational contexts, with off-the-shelf systems exhibiting Word Error Rates (WER) of up to 107.80% on Singaporean-accented aviation speech. We introduce ASTRA, an end-t
The increasing complexity of air traffic and the growing demand for ATCOs globally, coupled with the limitations of current training methods, are driving innovation in simulator technology.
This development addresses a critical bottleneck in air traffic control training through AI-driven autonomy, portending more efficient and scalable training, especially for non-Western operational contexts.
Training for Air Traffic Control Operators can become significantly more scalable and culturally relevant, reducing reliance on human role-play and improving accuracy in diverse linguistic environments.

ATCO training capacity increases, leading to a more robust global air traffic control workforce.
The successful application of AI to highly specialized, accent-specific voice environments could spur similar developments in other critical communication-dependent sectors.
Enhanced ATCO training systems could indirectly improve air travel safety and efficiency globally, especially in regions with unique linguistic challenges.
